Shock exposure. China did this aircraft carrier in the experimental equipment
Ma Weiming, 1996, graduated from Tsinghua University, Chinese Academy of Engineering, Rear Admiral. He led the successful development of the project to China’s conventional submarines, nuclear submarines successfully achieved all-electric propulsion, now presided over the aircraft carriers of electromagnetic catapult project, recently the Central Military Commission, for his special note of a first.the
in recognition of outstanding contributions in the field of scientific and technological innovation, Naval University of Engineering, Professor Weiming, recently Chairman of the Central Military Commission Hu Jintao signed the orders, he recorded a first.
Ma Weiming, Chinese Academy of Engineering, marine propulsion and electrical engineering experts, the Navy’s professional and technical rank of major general. He first proposed the theory of power integrated in the world, has overcome the constraints countries, the major technical difficulties for the development of military equipment of nearly a thousand, there are 20 achievements for the world’s first international leader. He presided over the completion of a completely independent intellectual property rights, as well as new submarines to provide high-quality AC and DC power supplies, AC-DC integrated dual-winding generator systems, won the 2010 National Science and Technology Progress Award.

high ground in the forefront of scientific research, as long as Ma Weiming see quasi-subject, even if no one put a cent, he will be out-of-pocket bite the bullet and break forward. Five years ago, he aimed at an international scientific and technological areas of cutting-edge technology, to apply to 100 million in demonstration funds. Demonstrate completion of the report, never give him to vote the money. The reason is simple: the country hundreds of millions of special research funding has been allocated to the counterpart research institutions. Ma Weiming stubborn strength full: Zaguomaitie, they have to dry! Come up with 20 million yuan from the accumulation of scientific research, led by the laboratory of a gang of young experts to work hard for two years, successfully developed a small prototype
end of the year 2008, more than 80 famous experts and scholars, including 7 academicians Qi Jihai Military Engineering University, participate in scientific and technological achievements of Academician Weiming appraisal meeting. Face of Academician Weiming and his pioneering work, all the people that scared Dodge, all the people went crazy.
yes, shocked! Passion of Liu Zhi the Nanyi, two lines of tears welling: This is the most two words I hear in the appraisal meeting site.
can be said that a stone arouses thousand waves! Liu Zhi re-sit down and emotional normalized complex calm: one is a specialized research institutions, which lasted for several years a cost of several hundred million dollars halfway through the dismount, the party is come up with results from two years of investment gold. Senior decision-makers embarrassed: follow-up investment is tilted to the the Weiming international leading technology, or are still slavishly followed the foreigners a few decades ago the path taken?
thrust long-range linear motor
a technological innovation and institutional innovation can not be less. System, 30 years of reform has not yet completely broken the planned economy era, the formation of a high degree of curing and fragmentation of the backward system of scientific research, still stifle the advancement of technology to deter the growth of innovation
Ma Weiming great creation is still a long way away from the celebration of the Arc de Triomphe, the next step is the development of the 1:1 prototype unit components. Alone needs at least at the expense of more than 50 million yuan. Money from? If the state does not invest, Weiming stubborn King put down hard: even if the borrowing debt within a year it dry out!
cast several hundred million dollars to the steam catapult, somewhat less than expected, so good, but rather self-financing out of the electromagnetic launcher technology, have seen the dawn. If the horse can come up within one year of full-size prototype, that 2010 should be to engage. This year’s winners is a natural progression. And see the caller bombs overwhelm the steam to become the next generation of preferred.
electromagnetic aircraft launching system – the key technology
electromagnetic catapult the heart is over 100 meters long linear induction motor, it pushes the armature connected with the aircraft. At present, the armature is basically a U-shaped aluminum block mounted on the stator 3 side. The principle of linear motor is not complicated. Conceived the induction motor of the rotary motion of a cut open along the direction of the radius, and flattening, which becomes a linear induction motor. In the linear motor, which is equivalent to rotating stator, called primary; equivalent to rotating the rotor, called the secondary. Primary pass in order to exchange, the secondary in the role of the electromagnetic force along the primary linear motion when the primary need to do is very long, extending to the movement needed to reach the location, and the sub is not required so long. In fact, the linear motor can either primary very long, can also be secondary very long; both can be fixed primary, secondary move, you can also sub-fixed primary move. However, the electromagnetic catapult is not linear motor alone, a total of forcing energy storage devices, high-power electrical control equipment, the central computer, industrial control and linear induction motor.
forced the energy storage device
force energy storage is a bottleneck of the electromagnetic catapult on defense has been highly classified. The role is usually charged, and then the high-power energy released in a short period of time. Electromagnetic catapult working hours is not long, but in the period of acting is a process of acceleration acting and therefore can not consider it as a constant power device.
electromagnetic catapult system in the forced energy storage system is full of energy requirements within 45 seconds. The largest aircraft carrier off the general energy consumption does not exceed 120 megajoules, which forced the energy storage system can store up to 140 megajoules of energy, the charging power of 3.1 MW, count the loss of about 4 MW (in fact, reach), four electromagnetic catapult system at the same time, charging that the total power of up to 16 MW (1 MW=1000KW), we can see no strong power is unable to meet the demand of electromagnetic catapult. Of course, the aircraft carrier on the power consumption is not limited to the four electromagnetic catapults, as well as electromagnetic rail guns, lifts, laser (laser power is not large), electricity combined must total power of the carrier 60 trillion watts or more, or electromagnetic catapult charging also affect other systems of electricity.
electromagnetic catapult challenge is the electrical energy like steam, does not suitable for mass storage, like storage catapult aircraft carrier energy is even harder. General Atomics was no mention of forced energy storage in the experimental electromagnetic catapult, showing the highly confidential nature of its technology is unusual to want to break the actual process is not easy
more is completed by the pulse generator. Steam catapults for the synchronous operation to shorten the take-off distance, to block the aircraft run with an iron bar, aircraft engine thrust can not be inferred iron bar, but with the catapult work together but can be inferred iron bar, so that the aircraft engine and catapult in the catapult and the engine work together to take off. Electromagnetic catapult without iron bars blocking the synchronization power of the electromagnetic catapult takeoff, but the current is gradually increase again, and take off the last paragraph of the current deadline.
a certain type of ship special power technology, currently only individual developed countries to master. The Weiming rate group set of intellectual research, with the world advanced level. However, no one believes that they can engage in out of China’s accumulated technology in this respect is not enough. Weiming cross summon up the resolve: “even have given ten years, but also capture the special power of technical difficulties!”
after five years of hard sprint, Ma Weiming lead the project team to complete the whole process of prototype development and testing of 43 key technologies have all been overcome, to declare the national defense patent 32. Chinese Academy of Sciences, 7 academicians of the Chinese Academy of Engineering review this major results excited that this major breakthroughs in key technologies, its as important as the “two bombs and one satellite and manned space flight.
